SI prefix conversion practice

SI Prefixes: pico = p = 10−12

nano = n* = 10−9

micro = μ* = 10−6

milli = m* = 10−3

centi = c* = 10−2

deci = d* = 10−1

kilo = k* = 103 mega = M* = 10

6 giga = G = 10

(* = memorize)

When setting up a conversion factor to or from a base unit, use 1 for the prefixed unit and the

power of 10 for the base unit. Example: 1 mg = 10-3

g; 1 kg = 103 g.

Give all answers in scientific notation. Practice setting these up as dimensional analysis

conversions with cancelling units.
